Huge issue with tail light, turn signal and brake light on driver side rear in my '65 GTO. Changed the light socket and bulb 3 times. When the bulb is in the socket the grounding strip on the socket has power and should be ground.

The passenger side works as it should. Front parking lights, turn signals, and headlights operate with no issues. In addition I had no instrument lights before the tail light fuse issue.

Disconnect the ribbon harness at the fuse box to eliminate the tail light issue.
When I turn the headlight switch on the tail light fuse shorts.

The brake light switch is working, this is a tilt column and the switch is working. I have blown a flasher and replaced it and now the driver side indicator light is not flashing, just lights up as if the bulb is out.

The whole deal seems to be getting worse. Could be corrosion, connections, but appears there is a dead short when the headlight switch is on. I have tried 4 headlight switches. Any ideas?
